Why accessibility overlays don't ensure compliance
Updated: 2026-06-09
Accessibility overlays are scripts that promise "automatic compliance" — in practice they don't fix the root cause and can trigger complaints.
What overlays are
An overlay is a JS/CSS script added to a page that tries to patch its appearance or behaviour at runtime instead of fixing the source code.
Why they don't ensure compliance
They don't remove real barriers in the code, often conflict with professional screen readers, and have been the subject of lawsuits. The accessibility community and regulators are critical of overlays as a compliance method.
EAAsy never uses overlays — it generates real fix code to apply in the page's source.
